The remote SMTP host that the message will be sent through. This is typically an SMTP server located at your local ISP or it could be an internal SMTP server on your companies premises. Up to 3 server addresses can be specified, separated by a semicolon. If the primary server is down the component will attempt to send the mail using the secondary server and so on. If your RemoteHost uses another port besides 25 then append a colon and port number to the RemoteHost value.
